Don’t fall for LPA ****

I’ve been ****med by LPA that called me to visit their offices to collect my voucher for accommodation. Did they not make fill in forms when I got there. The next thing I’m told before I can receive my voucher I need to enter into a contract. I refused it however, I had already given them my details. Now they are forcing me to pay a monthly subscription towards their holiday club. I indicated that I’m not interested but they keep debiting my account every month. I feel bul****. I’ve been wanting out of their contract but they won’t let me cancel!!!
